Installation in a rack
•
Check the earthing and stability of the rack, and make sure there is no obstacle inside or near
the rack that might hamper the installation.
•
Reserve sufficient space around the rack. For a closed rack, make sure the rack has good
ventilation.
Electrical safety
High voltage
Direct contact or contact through wet objects with high voltage power can result in fatal hazard.
Incorrect high voltage operation can cause fire and electric shock.
High leakage current
WARNING!
To avoid bodily injury or device damage, ground the device before powering it on if a "high leakage
current" label is attached to the power terminal on the device.
AC and DC power supply
WARNING!
•
Direct contact or contact through wet objects with the power source can result in electric shock.
•
Incorrect operation might cause accidents such as fire and electric shock.
•
If the device uses AC power input, each power supply must have a separate circuit breaker.
•
This device is suitable for TN power systems. It cannot be powered by an IT power system. If
your supplies are of the IT type, this unit must be powered by 230V (2P + T) via a 1:1 ratio
isolation transformer, and the Neutral wire on the secondary point must be connected to the
earth (ground) directly.
•
For devices that use a DC power source, use reinforced insulation or double insulation to
isolate the DC power source from the AC mains supply.
•
For devices that use an SELV/ES1 DC power source, use SELV/ES1 power source compliant
with IEC60950-1/IEC 62368-1.
•
For devices that use a DC power source, provide circuit breakers compliant with local power
supply regulations and make sure the circuit breakers are always available.
•
The device comes with high-voltage DC power supplies. Please use supplied or recommended
power cables to connect the power supplies.
